Well, the Internet Archive is now officially a library according to the State of California! It turns out that to receive a particular kind of federal funding, you have to have your state sign off that you are a library.
With a minimum amount of back and forth (including their saying "we have not evaluated something like the Internet Archive before") we were given the approval.
Nice to know!
I first heard about Internet Archive back in late '90s. The name "Wayback Machine" was also used interchangeably (I think that later got consolidated as "Internet Archive" when they archived more than just web sites).
More about the Internet Archive here.
BTW, I looked up "library" in my Mac's Oxford American dictionary (Version 1.0.1) and the entry says:
Noun ~ a building or room containing collections of books, periodicals, and sometimes films and recorded music for people to read, borrow, or refer to : a school library | [as adj. ] a library book.
• a collection of books and periodicals held in such a building or room : the Institute houses an outstanding library of 35,000 volumes on the fine arts.
• a collection of films, recorded music, genetic material, etc., organized systematically and kept for research or borrowing : a record library.
• a series of books, recordings, etc., issued by the same company and similar in appearance. • a room in a private house where books are kept.
• (also software library) Computing a collection of programs and software packages made generally available, often loaded and stored on disk for immediate use.
ORIGIN late Middle English : via Old French from Latin libraria ‘bookshop,’ feminine (used as a noun) of librarius ‘relating to books,’ from liber, libr- ‘book.’
I think it's time to update the opening paragraph and add another bullet point, so that the definition includes something like the Internet Archive (where the library and its collections isn't physical in the traditional sense).
